Hi, what do you mean by "mobile support"? The Legacy Edition is already playable in mobile browsers. Additionally, a mobile version is in development (for now, Android only). An older build is already available for download on Itch.
As for "controller support," it’s a bit complicated. Technically, you can already map inputs and control the player, but there’s no aim assist, and certain actions still require a mouse and keyboard. Adding proper controller support would require replacing the entire input system and reworking much of the UI, so I’m not sure if SW will have full controller support. But we’ll see.
